No footnotes, no endnotes, not the slightest proof. Just hundreds of pages of flowery exposition on how great Negroes are.
The author is also misleading in many claims. Stating that men such as Tertullian were African, when, actually, he was born in the Roman province of Africa. A play on words, Tertullian was no more African (black) than I would be Japanese were I born in Tokyo. I would be a White man living in Japan.
Pro-Black propaganda trying to give a suitable backstory to a race that has accomplished nothing of note. Even those relative few brought to the United States as slaves accomplished nothing and their descendants aren't African--they are hybrids that shouldn't have existed to begin with.
Even with an infusion of White genetics these faux-Africans still cannot compete without the need to have educational standards lowered or removed (in the interests of equality, of course).
It comes down to Africans (of any admixture) are one of the dead-ends of humanity. The further one looks back in the literature the more obvious it becomes. This is why so-called Black History Month doesn't celebrate ANYTHING that is actually African, but only in relation to their so-called "400 years of enslavement" (which was actually 246 years, from 1619 to 1865) and anything after that point.
They (blacks) have no measurable history earlier than that to be proud about. Just cannibalism, witchcraft and endless in-fighting stretching back multiple millennia. The same as Africans of today behave without White guidance. One only has to look at Sub-Saharan Africa, Liberia, Zimbabwe, Hatti and the Congo for some examples.
The idea these creatures would be space-faring and highly civilized if not for "colonialism" is a farce so massive as to be laughable. Similarly, any race claiming two-and-a-half centuries of slavery derailed their civilization for all time never had one to start with.
Many colors have been enslaved, including Whites, it didn't slow them down. Grow up.
